DC Motors
WEG DC motors are designed with state-of-the-art project technology, resulting in compact machines
with excellent dynamic properties able to meet the requirements of a variety of applications in the
automation and process control areas.
Technical Characteristics
WEG DC motor line comprises a power range up to 10,000 kW,
with torques from 2 to 200,000 Nm, and is used in different
industrial applications, such as the paper and plastic industries,
among others.
Projected for drive by means of thyristor converters, the DC motors
can be manufactured with voltages from 110 to 1000 V and frame
sizes (IEC) from 90 to 1800, or larger sizes upon consultation.
Powers up to 10,000 kW

Constructive Characteristics
Frame
Laminated in high-quality steel plates in rectangular, hexagonal
or octagonal shape, allowing supply by static converters in high
dynamic duties with fast torque and current variations.
Rotor and Stator Winding
They are wound with copper wire enamel-coated with class H
varnish and with insulation and impregnation system class F or H.
Endshields
In cast iron or welded, they allow the coupling of WEG
tacogenerators model 1R or TCW and other accessories,
tacogenerators and encoders upon consultation.
Commutators
Made of copper and with the highest quality insulating materials,
they allow a perfect contact with the brushes and ensure excellent
commutation conditions.
Brush Holder
Manufactured with high technology, they have dimensions,
tolerances and pressures suitable for each application, ensuring a
long useful life of the mechanical system.
Brushes
Made of electrographite, natural graphite or specified according to
load conditions, they ensure a long useful life.
Bearings
Ball bearings or roller bearings according to the size and
application of the motor.
Oil-lubricated sleeve bearings for specific applications.
